Self-esteem

I don't know what to do right now. I don't have any self-esteem (I mean absolutely none). I feel like I'm a huge disappointment to everyone around me. I feel like I'm a waste of space, time, energy, resources. I don't want to do anything because I know I'll fail. I know I don't deserve to be loved or to have friends. I don't have dreams or hopes. I have nothing to look forward to. I only ever wanted one thing: to have a child. It's been 12 years since I had to have a hysterectomy because I had cancer and every commercial with babies in it still makes me cry. I feel like my whole life is a waste.
